Energy dissipation method and an Iterative Bulk Aerodynamic Method (IBAM) are used to estimate friction velocity (u*) for a wide wind speed range (5.66 to 21.6 ms −1 ) with convective atmospheric conditions over the ocean during the Genesis of Atlantic Lows Experiment (GALE). Values of u* obtained by the IBAM are in reasonably good agreement with those from the dissipation method. The iterative bulk method appears to do well for wind speeds up to about 21 ms −1 .
